The main plots were planting pattern (row distance 30, 45 and 60 cm) and sub plots were five levels of nitrogen (0, 40, 80, 120 and 160 Kg/ha of pure nitrogen) as urea. In this study some plant properties such as seed yield, seed number in head, the number of head in plant, 1000 seed weight, oil seed percent, oil seed yield, biological yield, seed protein percent and leaf nitrogen percent were measured. The results show the highest seed yield (2229 kg/ha) and the highest oil yield (691 kg/ha) were made with 60 cm row distance and 80 kg/ha of pure nitrogen, That was 54 and 59.2 percent higher than control. The highest number of seed in head (88.67) that was the most important yield component was obtained from 60cm row distance and 80 kg/ha of pure nitrogen. The highest oil seed percent (31.7) was obtained from 60cm row distance and 40 kg/ha of pure nitrogen and highest protein seed percent (14.62) was obtained from 60cm row distance and 160 kg/ha of pure nitrogen. The difference between oil and protein percent show an opposite relation when increasing nitrogen fertilizer levels. By considering the our results, 60cm row distance and 80 kg/ha of pure nitrogen for this safflower cultivar in similar conditions to the experiment is suitable.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83535

Five level pre-sowing nitrogen from the source of urea wasapplied in amounts of 0(as control), 120, 160, 200 and 240 kg/h. Chlorophyllconcentration leaf blade number 5 was measured by chlorophyll meter (SPAD) at12-15 leaf stage. In the same leaves, concentrations of nitrogen (by Kjeldahl method) wasmeasured. The results showed that moreover 50% of the variability in yield isexplained by the SPAD reading in the growth stages 12-15 leaf in sugar beet. SPADvalue was, also related whit N concentration and α- amino N in root. Thehighest SPAD reading showed maximum α- amino N in root. Nitrogen fertilizer hadsignificant effect on the chlorophyll meter reading. The least number read fromSPAD was 38, which associated with no-applied nitrogen treatment. highest yieldof root (ton / hac) in this experiment was related to with N160, which the number read from thechlorophyll meter in levele was equal with 41/2. According to the obtainedresults, therefore, whit further research chlorophyll meter (SPAD) can be usedas a simple rapid and non- destructive and may be useful to predict yield andmay be a useful tool determine which field to harvest late in season.

A.SajediDepartment of Agronomy and Plant Breeding, Arak Branch, Islamic Azad University, Arak, Iranauthortextarticle2011per Early, fast and uniform seed germination results in favorable emergence and greater early vigor, which in turn leads to more radiation interception and higher yield. In order toinvestigation of effectives of different concentrations of sodium hypochlorite and different times of disinfestations on wheat seed of infection to Aspergillus fungi, testing in the laboratory seed Technology in National Date Research center. This study was performed by factorial in random complete deign whit three block. These treatments are utilized four concentrations 2, 4, 6, 8 sodium hypochlorite percentage and four times 2, 5, 7, 10 min and two witness (healthy seed and lack of infection and infection seed to Aspergillus fungi and without treatment). The results of variance analyzing indicated that there was significant (p<0.05) effectives of concentration and times of utilized sodium hypochlorite on length rootlet, length shoot let, dry weight shoot let, dry weight rootlet. The most length is rootlet concerned to concentration 4% and length shoot let is concerned to concentration 6% , 7 min and dry weight shoot let and dry weight rootlet are concerned to concentration 8% , 5 min. It was concluded that it is possible to use the concentrations differences found in this research to improve the components of germination under suboptimal temperatures and it is also possible to improve the base and optimal temperatures in wheat.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83535

Treatments were consisted of two potato cultivars “ Agria and Markyz” in main plots and utilization and non utilization of zinc sulfate and with and four levels Phosphorus solublizing bacteria were in sub plots. Experiment model was spilt factorial in three replicates at 2010. Treatments were two potato cultivars Agria and Markyz, and two levels of Zink foliar application and without and phosphorus utilization in four levels included 100 kg/ha triple super phosphate, Triple super phosphate 100 kg/ha and PSB bacteria, PSB alone, and 50 kg/ha triple super phosphate with PSB. The results showed that the biomass yield, plant height, potato tubers numbers per plant and tuber yield had significant difference by applied experiment treatments. The results also suggest that all potato traits studied were significant advantages compared to Markyz to control. In all cases of PSB utilization with chemical phosphorus fertilizer we observed that potato characteristics were improved. Agria was more sensitive than Markyz about phosphate availability. In low phosphate condition, Markyze potato tubes dry weight was reduced from 81 to 51 g. this changes was from 66 to 54 g for Agria cultivar too.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83535

Results showed that irrigation method had significant effect on tuberyield and water was efficiency at 0.01 and on tuber number and tuber meanweight at 0.05 also on plant pattern had significant effect. Tuber yield,biomass weight and water use efficiency at 0.01 Variety effect on all elementswas significant at 0.01. Treatment of drip irrigation method had the most tuberyield with 50014 Kg/h which it was more than sprinkle irrigation method with22037 Kg/h. Day irrigationhad more yield in comparison with highirrigation. The treatment of sante variety with trickle and day irrigation andplant pattern of 65×23cm, had the most yield with 5547 kg/h and itis recommended for this region.New Finding in AgricultureIslamic Azad University, Arak Branch1735-83535
